Drug invoice problem

Why do you ask for a sales invoice when you know that the drug is in a pharmaceutical company? Large pharmacies belong to retail terminals, and pharmaceutical companies belong to distribution. A big pharmacy must have a file with the pharmaceutical factory where you put the medicine, and the sales department of the pharmaceutical factory can make out an invoice, transfer money or cash according to the wardrobe of that big pharmacy. Of course, as a manufacturer's agent, you can go to the terminal sales department of the pharmaceutical company or the department that can invoice the big pharmacy. According to different companies, the names are naturally different. The fare is the price you are willing to charge the pharmacy, but you must be able to pass the computer of the pharmaceutical factory. In other words, on the basis of your supply price, you can guarantee the distribution points of pharmaceutical companies (depending on the asking price of each company, ranging from 6 to 50 points), let the salesmen of pharmaceutical companies invoice and deliver them to the big pharmacy after picking up the goods. Simply put, this is the process. Therefore, the big pharmacy said that you should issue an invoice to the pharmaceutical company, but the issuing bank (customer name) should be this big pharmacy. The price offered by the salesman of the pharmaceutical company to this pharmacy is the fare, which is usually at the lowest point, and the price of the big pharmacy is slightly lower. If the salesman of the pharmaceutical company allows you to resell, it is not bad to offer the price you promised to the big pharmacy. Of course, it is necessary for you to make up the difference later.
